Propanoic acid derivatives as intergrin receptor antagonists

ABSTRACT

Novel propanoic acid derivatives are integrin receptor antagonists or inhibitors, in particular of the avb3 integrin receptor. The compounds of the invention are for instance useful for the treatment of solid tumors by inhibition of angiogenic growth of tumor vessel network, thus promoting tumor regression, inhibition of metastatic spread, thus avoiding cancer metastases, inhibition of bone resorption, thus controlling osteoporosis, inhibition of smooth muscle cells migration into neointima, thus blocking restenosis after percutaneous coronary angioplasty and the treatment of other pathological conditions mediated by cell adhesion, cell migration or angiogenesis such e.g. diabetic retinopaty, rheumatoid arthritis and inflammation.

[0001] The present invention relates to novel non-peptide compounds which bind to the integrin receptor αvβ3, to pharmaceutical compositions containing such compounds, processes for preparing such compounds, and to methods of using these compounds, alone or in combination with other therapeutic agents. Integrins are membrane-bound receptors that mediate cell-matrix and cell-cell adhesion interactions. The compounds of present invention are useful for the treatment of diseases in which the pathology arises from ligation of an integrin receptor, especially the vitronectin receptor, and therefore of diseases mediated by cell adhesion and angiogenesis. The compounds of present invention are useful in selectively inhibiting or antagonizing αvβ3 integrin and therefore are useful for the treatment of solid tumors by inhibition of angiogenic growth of tumor vessel network, thus promoting tumor regression, inhibition of metastatic spread, thus avoiding cancer metastases, inhibition of bone resorption, thus controlling osteoporosis, inhibition of smooth muscle cells migration into neointima, thus blocking restenosis after percutaneous coronary angioplasty and the treatment of other pathological conditions mediated by cell adhesion, cell migration or angiogenesis such e.g. diabetic retinopaty, rheumatoid arthritis and inflammation. The utility of antagonists of the αvβ3 integrin and related cell surface adhesive protein receptors is well known in the art.

[0481] Process-Variants a) to l), Respectively, Can for Instance be Carried out at Follows:

[0482] a) In a typical procedure the acid was added to a large excess of thionyl chloride (25 equivalents) kept under stirring at about 0° C. under nitrogen atmosphere, the mixture heated at about 60° C. for 1 hour, brought to room temperature and thoroughly evaporated in vacuo. The acid chloride II was dissolved in DMF and added to a mixture of the intermediate required (III) (1 equivalent) and triethylamine (1 equivalent) in DMF or pyridine. The mixture was stirred at room temperature for 48-72 hours, the solvent removed, the residue taken with brine and extracted with dichloromethane. The compounds thus obtained were purified by silica gel flash chromatography eluting with CH₂Cl₂/MeOH 9:1.

[0483] b) In a typical procedure compounds of formula IV were added to a solution of V in solvents like DMF, acetone, in presence of a base (NaH, K₂CO₃, KHMSA) the temperature varying between room temperature and reflux, the time of reaction varying between 24-72 hours. The mixture filtered the solvent evaporated and the residue taken with brine and extracted with dichloromethane or ethyl acetate. The compounds were purified by silica gel flash chromatography eluting with CH₂Cl₂/MeOH 9:1 or Petroleum ether 40-60/Ethyl acetate 1:1.

[0484] c) In a typical procedure the amino derivatives of formula VI reacted with the guanilating agent, such as di-Boc-triflyl-guanidine, in dichloromethane in presence of stechiometric amounts of base such as triethylamine or diusopropylethylamine, the time of reaction varying between 24-72 hours. The compounds thus obtained did not request further purification. (FEICHTINGER, K.; ZAPF, C.; SINGS, H. L.; GOODMAN, M.; J Org 1998, 63 (12), 3804-3805). The protection groups were removed according to standard procedures, with TFA.

[0485] d) In a typical procedure the amino derivatives of formula VI reacted with a cyanate salt, as e.g. a ammonium or sodium or potassium salt, in solvent such as AcOH, H₂O (Org. Synth. 1963, IV, 49) PNAS 1993, 90, 6909-6913) the temperature varying between 50-100° C., the time of reaction varying

[0486] e) In a typical procedure the amino derivatives of formula VI reacted with isocyanates in presence of triethylamine refuxing in solvents such as dichloromethane, acetonitrile, toluene or dioxane (JMC 1996, 39 (22) 4382-4395; Eur J Med Chem 1997, 32 (10), 795-804.) to give the subtituted ureas, the temperature varying between room temperature and reflux, the time of reaction varying between 8-24 hours.

[0487] f) In a typical procedure to a stirred solution of the acids VIII (cinnamic or trans-3-(3-pyridyl)acrylic) as ethyl esters or polymer supported, in dichloromethane kept under vigorous stirring in nitrogen atmosphere, the amiothiophenols VII (2eq) and DBU(0.1 equivalent) were added, the mixture was stirred at room temperature for about 24 hours, the solvent evaporated and the residue purified by silica gel flash chromatography eluting with petroleum ether 40-60/ethyl acetate 1:1, to give the intermediates required.

[0488] g) In a typical procedure compounds of formula X were added to a solution of IX in solvents like DMF, acetone, in presence of a base (K₂CO₃, NaH, KHMSA) the temperature varying between room temperature and reflux, time of reaction varying between 8-24 hours

[0489] h) The ester compounds of formula I, were hydrolysed by treatment with a mixture of HCl 4N and ethanol overnight. Solvents were evaporated and the final compounds, obtained as hydrochlorides, purified by crystallisation with methanol and ether.

[0490] i) The sulfur functions of formula I were oxidised to solfones with 30% aq H₂O₂ (RAVIKUMAR, K. S.; BEGUE, J. -P.; BONNET-DELPON, D.; Tetrahedron Lett 1998, 39 (20), 3141-3144.) or with NaIO₄, in water and methanol, or acetone and water, according to a standard procedure (BEIER, C.; SCHAUMANN, E.; Synthesis 1997, (11), 1296-1300; LE MERRER, Y.; FUZIER, M.; DOSBAA, I.; FOGLIETTI, M. -J.; DEPEZAY, J. -C.; Tetrahedron 1997, 53 (49), 16731-16746.). The sulfur functions were oxidised to solfoxides according to a standard procedure by reacting with oxone in a mixture methanol/water as a solvent (HINTERBERGER, S.; HOFER, O.; GREGER, H.; Tetrahedron 1998, 54 (3), 487-496.)

[0491] l) Compounds of formula I linked to the Wang resin were cleaved as a final step with a mixture trifluoroacetic acid/dichloromethane, the time of reaction varying between 15-30 minutes.

[0492] Also the optional salification of a compound of formula (I) as well as the conversion of a salt into the free compound and the separation of a mixture of isomers into the single isomers may be carried our by conventional methods. For example, the separation of optical isomers may be carried out by salification with an optically active base or acid and by subsequent fractional crystallization of the diastereoisomeric salts, followed by recovering of the optically active isomeric-acids or, respectively, bases. When in the compound of formula (I), and in the intermediate products thereof, groups are present which need to be protected before submitting them to the here-above illustrated reactions, they may be protected before the reactions take place and then deprotected, according to well known methods in organic chemistry.

[0890] Pharmacology

[0891] The compounds of the invention are selective integrin receptor inhibitors or antagonists, in particular of the αvβ3 integrin receptors. The specific inhibiting or antagonist activity of the compounds of the invention is shown for instance by the fact that they are active in in vitro solid phase αvβ3-vitronectin binding assay, as described below.

[0892] αvβ3-vitronectin binding assay

[0893] A solid phase assay for the study of αvβ3-vitronectin binding was set up on the basis of already published methods (Wong et al, Molecular Pharmacology 50: 529-537, 1996; Brooks et al., Cell 85: 683-693, 1996). The human αvβ3 integrin was diluted into coating buffer (CB) containing 150 mM NaCl, 1 mM CaCl₂, 1 mM MgCl₂, 1 mM MnCl₂, 20 mM TRIS, pH 7.4 at a concentration of 1.5 μg/ml. Into 96-well plates, 50 μl of the diluted integrin were added and allowed to bind to the plate walls overnight at 4° C. Next day, the assay plates were emptied and 100 μl of blocking buffer (CB buffer with 3% BSA) were added to each well for 45 min at 37° C. After the incubation, the plates were washed three times with 100 μl assay buffer (AB, CB buffer with 0.1% BSA); serial 1:1 dilution (25 μl/well) of the test compounds were added to the plates, starting from 10 mM solutions in 100% DMSO diluted to 100 μM in AB. The binding reaction was started by addition (25 μl/well) of 10 nM biotinylated vitronectin (final concentration: 5 nM), and lasted 30 min at 37° C. The concentration range of the tested compounds spanned from 50 to 0.0005 μM. At the end of the co-incubation, the assay plates were washed as before and 70 μl of a 1:1000 AB dilution of peroxydase-conjugated streptavidin were added per well and were allowed to react for 45 min at 37° C. Then, the plates were washed as described and 50 μl of ready to use Turbo-TMB substrate for peroxydase were added to each well. After 30 minutes incubation at room temperature, the color development was stopped with 50 μl sulphuric acid 0.38 M and the plates were read at a wavelength of 450 nm with a Packard plate reader. The values obtained were analyzed by four parameters curve fit in the computer program GraphPad Prism, after normalization by a maximum binding control (Bmax) detected in wells where no competitor was added, and a minimum binding control (NSB) detected in wells where no integrin was coated. Under standard assay conditions, A₄₅₀ was never under 1.0 for Bmax, and around 0.15 for NSB. The computerized algorithm gave the concentration of compound needed to inhibit the maximum binding by 50% (IC₅₀ value): for those compounds that did not inhibit this binding by 50% at the highest concentration tested, IC₅₀ value was reported as being greater then the highest concentration tested. As a positive control, increasing doses of a peptide containing the RGD sequence was added to each plate: IC₅₀ value of this molecule was 120 nM.

[0894] Materials

[0895] Human vitronectin receptor (αvβ3) was purified from human placenta (Pytela et al, Methods in Enzymology, 144: 475-489, 1987). Turbo-TMB was from PIERCE (34022). BSA (A4503), Vitronectin (V8379), RGD peptide (G4144) and all generic reagents were from SIGMA. Vitronectin was biotinylated according to the procedure indicated in the NHS biotinylation kit from PIERCE (21420). Horseradish peroxydase-streptavidin was from Amersham (RPN1231). 96-well plates were from Costar (#3690, EIA/RIA plate, 1/2 area flat bottom, high binding).

[0896] αIIbβ₃-fibrinogen binding assay

[0897] A solid phase assay for the study of αIIbβ₃-fibrinogen binding was set up on according to the method described for αvβ3. αIIbβ₃ integrin was diluted into coating buffer (CB) containing 150 mM NaCl, 1 mM CaCl₂, 1 mM MgCl₂, 1 mM MnCl₂, 20 mM TRIS, pH 7.4 at a concentration of 3 μg/ml. Into 96-well plates, 50 μl of the diluted integrin were added and allowed to bind to the plate walls overnight at 4° C. Next day, the assay plates were emptied and 100 μl of blocking buffer (CB buffer with 3% BSA) were added to each well for 45 min at 37° C. After the incubation, the plates were washed three times with 100 μl assay buffer (AB, CB buffer with 0.1% BSA); serial 1:1 dilution (25 μl/well) of the test compounds were added to the plates, starting from 10 mM solutions in 100% DMSO diluted to 100 μM in AB. The binding reaction was started by addition (25 μl/well) of 20 nM biotinylated fibrinogen (final concentration: 10 nM), and lasted 30 min at 37° C. The concentration range of the tested compounds spanned from 50 to 0.0005 μM. At the end of the co-incubation, the assay plates were washed as before and 70 μl of a 1:1000 AB dilution of peroxydase-conjugated streptavidin were added per well and were allowed to react for 45 min at 37° C. Then, the plates were washed as described and 50 μl of ready to use Turbo-TMB substrate for peroxydase were added to each well. After 30 minutes incubation at room temperature, the color development was stopped with 50 μl sulphuric acid 0.38 M and the plates were read at a wavelength of 450 nm with a Packard plate reader. The values obtained were analyzed by four parameters curve fit with the computer program GraphPad Prism, after normalization by a maximum binding control (Bmax) detected in wells where no competitor was added, and a minimum binding control (NSB) detected in wells where no integrin was coated. Under standard assay conditions, A₄₅₀ was never under 0.8 for Bmax, and around 0.15 for NSB. The computerized algorithm gave the concentration of compound needed to inhibit the maximum binding by 50% (IC₅₀ value): for those compounds that did not inhibit this binding by 50% at the highest concentration tested, IC₅₀ value was reported as being greater then the highest concentration tested. As a positive control, increasing doses of a peptide containing the RGD sequence was added to each plate: IC₅₀ value of this molecule was 2.3 μM for αIIbβ₃-fibrinogen binding.

[0898] Materials

[0899] Human fibrinogen receptor (αIIbβ₃) was purified from human platelets ((Pytela et al, Methods in Enzymology, 144: 475-489, 1987). Turbo-TMB was from PIERCE (34022). BSA (A4503), fibrinogen (F4883), RGD peptide (G4144) and all generic reagents were from SIGMA. Fibrinogen was biotinylated according to the procedure indicated in the NHS biotinylation kit from PIERCE (21420). Horseradish peroxydase-streptavidin was from Amersham (RPN1231). 96-well plates were from Costar (#3690, EIA/RIA plate, 1/2 area flat bottom, high binding).

[0900] Cell Based Assay

[0901] Cell Line

[0902] Adhesion assay to vitronectin is performed using CEM (human leukemia cell line) stably transfected with cDNAs encoding human α_(v) and β₃ integrin subunits. The CEM D9 clone, expressing high levels of α_(v) β₃ integrin as confirmed by western blotting, was selected for the assay. The binding of CEM D9 to vitronectin is completely inhibited by anti-α_(v)β₃ monoclonal antibody LM609.

[0903] Coating Plate

[0904] Vitronectin (Sigma) is diluted to 10 μl/ml in DPBS (Dulbecco's phosphate buffered saline), dispensed 50 μl/well in 96 well high binding RIA/EIA plates (Costar) and allowed to coat overnight at 4° C. For blank 50 μl/well of heat denatured 3% BSA solution (bovine serum albumin), is dispensed. Plates are washed once with DBPS and saturated with 200 μl/well of 3% BSA, for 2 h at 37° C. At the end of incubation, each well is washed once with DBPS.

[0905] Adhesion Assay

[0906] For the assay, cells in log phase of growth are used. The cellular suspension is centrifuged at 1500 rpm for 8 min., washed with 10 ml of HBSS, resuspended in fresh complete medium and activated with 1 ng/ml PMA (Phorbol Miristate Acetate) for 1 h at 37° C. After incubation, cells are washed, counted, and diluted to a density of 1.6×10⁶ cells/ml in adhesion medium (0,1% heat denaturated BSA in HBSS+1 mM MnCl₂).

[0907] 10 μl of adhesion medium containing inhibitors at suitable concentrations are added to test wells. 90 μl/well of cell suspension is plated and incubated for 1 h at 37° C. Following adhesion, plates are gently washed twice with 200 μl of DPBSS and cells are fixed with 50 μl TCA 50% (tricloroacetic acid) for 1 hour at 4° C. Evaluation of cell adhesion is performed by staining with sulforhodamine B (1).

[0908] Parameters of Evaluation

[0909] The percentage of relative adhesion (RA %) is calculated using the following formula: $\% = {\frac{\begin{matrix} {{{average}\quad {of}\quad {O.D.\quad \left( {570\quad {nm}} \right)}\quad {of}\quad {treated}\quad {cells}} -} \\ {{average}\quad {of}\quad {O.D.\quad {of}}\quad {blank}} \end{matrix}}{\begin{matrix} {{{average}\quad {of}\quad {O.D.\quad \left( {570\quad {nm}} \right)}\quad {of}\quad {control}\quad {cells}} -} \\ {{average}\quad {of}\quad {O.D.\quad {of}}\quad {blank}} \end{matrix}} \times 100}$

[0910] Where O.D. is the optical density of wells at 570 nm, using a EL 340 plate reader. IC₅₀ is the dose inhibiting 50% of cell adhesion.

[0911] For example, compound 3-({4-[(3-{[amino(imino)methyl]amino}benzoyl)amino]-phenyl}sulfanyl)-3-(3-pyridinyl)propanoic acid (company code PNU 277362F), when tested in αvβ3-vitronectin and αIIbβ3-fibrinogen biding assays, gave the following activity data:

[0912] αvβ3(IC₅₀ μmol)=0.016±0.009

[0913] αIIbβ3(IC₅₀ μmol)=9.8±4.8

[0914] These test data show that compound 3-({4-[(3-{[amino(imino)methyl]amino}-benzoyl)amino]-phenyl}sulfanyl)-3-(3-pyridinyl)propanoic acid is endowed with high selective αvβ3 inhibiting activity. In fact, the ratio between αIIbβ3 and αvβ3 inhibiting activity is about 600.

[0915] In view of their high selective αvβ3 inhibiting or antagonizing activity, the compounds of the invention can be used in medicine in treating conditions mediated by the αvβ3 integrin. Accordingly, the compounds of the invention are useful for instance for treating various conditions or disease states including osteoporosis, humoral hypercalcemia of malignancy, Paget's disease, tumor metastasis, solid tumor growth (neoplasia), angiogenesis including tumor angiogenesis, retinopathy including diabetic retinopathy, arthritis including rheumatoid arthritis, psoriasis, periodontal disease, smooth muscle cell migration and restenosis in a mammal in need of such treatment. Additionally, such pharmaceutical agents are useful as antiviral agents, and antimicrobials.

[0916] According to a preferred object of the invention the αvβ3 inhibiting activity results in an anticancer therapy having increased effectiveness in controlling, i.e., slowing, interrupting, arresting, stopping or reversing, the neoplasm formation.

[0917] The compounds of the invention can be administered in a variety of dosage forms, e.g. suspensions; rectally, in the form of suppositories; parenterally, e.g. intramuscularly, or by intravenous injection of infusion; or topically.

[0918] The dosage regimen for the compounds and/or compositions containing the compounds is based on a variety of factors, including the type, age, weight, sex and medical condition of the patent; the severity of the condition; the route of administration; and the activity of the particular compound employed. Thus the dosage regime may vary widely. Dosage levels of the order from about 0.01 mg to about 1000 mg per kilogram of body weight per day are useful in the treatment of the above-indicated conditions and more preferably of the order from about 0.01 mg to about 100 mg/kg of body weight. For instance, the dosage adopted for oral administration to adult humans for compound PNU 277362F may range from about 0.01 mg to about 800 mg/kg of body weight per day and more preferably of the order from about 0.01 mg to about 750 mg/kg body weight.

[0919] When given parenterally a suitable daily dose for instance for compound PNU 277362F would typically be about 0.01 to 100 mg/kg body weight injected per day in multiple doses depending on the factors listed above and more preferably from about 0.01 mg to about 10 mg/kg body weight.

[0920] The invention includes pharmaceutical compositions comprising a compound of formula (I) or a pharmaceutically acceptable salt thereof in association with a pharmaceutically acceptable excipient (which can be a carrier or diluent).

[0921] The pharmaceutical compositions containing the compounds of the invention are usually prepared following conventional methods and are administered in a pharmaceutically suitable form.

[0922] For example, the solid oral forms may contain, together with the active compound, diluents, e.g. lactose, dextrose, saccharose, cellulose, corn starch or potato starch; lubricants, e.g. silica, talc, stearic acid, magnesium or calcium stearate, and/or polyethylene glycols; binding agents, e.g. starches, arabic gums, gelatin, methylcellulose, carboxymethylcellulose or polyvinyl pyrrolidone; disaggregating agents, e.g. a starch, alginic acid, alginates or sodium starch glycolate, effervescing mixtures; dyestuffs; sweeteners; wetting agents, such as lecithin, polysorbates, laurylsulphates; and, in general, non-toxic and pharmacologically inactive substances used in pharmaceutical formulations. Said pharmaceutical preparations may be manufactured in known manner, for example by means of mixing, granulating, tabletting, sugar-coating or film-coating processes.

[0923] The liquid dispersion for oral administration may be, e.g., syrups, emulsions and suspensions.

[0924] The syrup may contain as carrier, for example, saccharose or saccharose with glycerine and/or mannitol and/or sorbitol.

[0925] The suspensions and the emulsions may contain as carrier, for example, a natural gum, agar, sodium alginate, pectin, methylcellulose, carboxymethylcellulose or polyvinyl alcohol.

[0926] The suspensions or solutions for intramuscular injections may contain, together with the active compound, a pharmaceutically acceptable carrier, e.g. sterile water, olive oil, ethyl oleate, glycols, e.g. propylene glycol, and, if desired, a suitable amount of lidocaine hydrochloride.

[0927] The solutions for intravenous injections or infusion may contain as carrier, for example, sterile water or, preferably, they may be in the form of sterile aqueous, isotonic saline solutions.

[0928] The suppositories may contain, together with the active compound, a pharmaceutically acceptable carrier, e.g. cocoa-butter, polyethylene glycol, a polyoxyethylene sorbitan fatty acid ester surfactant or lecithin.

[0929] Compositions for topical application, e.g. creams, lotions or pastes, can be prepared by admixing the active ingredient with a conventional oleaginous or emulsifying excipient.

[0942] 1) a compound of the invention, or a pharmaceutically acceptable salt thereof, and

[0943] 2) an additional antitumor agent, in amounts and close enough together in time sufficient to produce a therapeutically useful effect.

[0944] The present invention also provides a product containing a compound of the invention, or a pharmaceutically acceptable salt thereof, and an effective antineoplastic amount of additional antitumor agent as a combined preparation for simultaneous, separate or sequential use in anti-cancer therapy.

[0945] Object of the present invention is to provide the use of a compound of formula (I), as herein defined, or a pharmaceutically acceptable salt thereof, in the preparation of a medicament having αvβ3 integrin inhibiting or antagonizing activity for controlling the growth of the neoplasm in a method additionally comprising the administration of an antitumor agent.

[0946] The combination preparation according to the invention can also include combination packs or compositions in which the constituents arc placed side by side and can therefore be administered simultaneously, separately or sequentially to one and the same human being. Accordingly, the antineoplastic agent and a compound according to the present invention may be present within a single or distinct container means. In the combined preparations, pharmaceutical compositions and methods of treating, according to the present invention, the antineoplastic agent may comprise 1 to 4, preferably 1, 2 or 3, antineoplastic drugs, in particular a single antineoplastic drug. As used herein, “controlling the growth” of the neoplasm refers to slowing, interrupting, arresting or stopping its growth and it does not necessarily indicate a total elimination of the neoplasm. It is believed that prolonging the survivability of a patient, beyond being a significant advantageous effect in and of itself, also indicates that the condition is beneficially controlled to some extent.

[0947] The term “antineoplastic agent” is meant to comprise both a single antineoplastic cytotoxic drug and “cocktails”, i.e. mixtures of such drugs, according to the clinical practice.

[0948] As used herein, the term “effective antineoplastic amount” refers to an amount which is effective, upon single or multiple dose administration to the patient, in controlling the growth of the neoplasm or in prolonging the survivability of the patient beyond that expected in the absence of such treatment.

[0949] An antineoplastic agent, according to the invention, is preferably selected from the group comprising: an antineoplastic topoisomerase II inhibitor, an antineoplastic antimicrotubule agent, an antineoplastic alkylating agent, an antineoplastic antimetabolite and an antineoplastic topoisomerase I inhibitor.

[0950] An antineoplastic topoisomerase II inhibitor is preferably:

[0951] a) an anthracycline compound e.g. doxorubicin (including liposomal formulations) daunomycin, methoxy-morpholino-doxorubicin, epirubicin (including liposomal formulation), idarubicin and nemorubicin; and

[0952] b) an anthraquinone compound e.g. mitoxantrone and losoxantrone; and

[0953] c) a podophillotoxine compound e.g. etoposide and teniposide.

[0954] An antimicrotubule agent is preferably:

[0955] a) a taxane compound e.g. paclitaxel (including liposomal formulations) and docetaxel; and

[0956] b) a vinca alkaloid e.g. vinblastine and vinorelbine.

[0957] An alkylating agent is preferably cyclophosphamide, ifosfamide, chlorambucil, melphalan and PNU 159548 (C. Geroni et al., Proc. Am. Assoc. Cancer Res 39, p223, 1998 (Abstr. #1517).

[0958] An antineoplastic antimetabolite agent is e.g. 5-fluorouracil, capecitabine, gemcitabine, methotrexate and edatrexate.

[0959] An antineoplastic topoisomerase I inhibitor is e.g. topotecan, irinotecan, 9-nitrocamptothecin and PNU 166148 (Compound A1 in WO 99/17804).

[0960] An antineoplastic agent is in particular epirubicin, doxorubicin, liposome-encapsulated doxorubicin, docetaxel, paclitaxel and liposome-encapsulated paclitaxel.

[0961] Particularly preferred preparations, pharmaceutical compositions and methods of treating, according to the present invention, are those comprising a) 1, 2 or 3 antineoplastic agents selected from epirubicin, doxorubicin, idarubicin, paclitaxel, docetaxel, 5-fluorouracil, cyclophosphamide and vinorelbine, and b) a compound of the invention or a pharmaceutically acceptable salt thereof.

[0962] The effective antineoplastic amounts of the various antineoplastic agents are well known and appreciated in the art.

[0963] For example, an effective antineoplastic amount of vinblastine may vary from about 3 mg/m² to about 10 mg/m².

[0964] An effective antineoplastic amount of doxorubicin may vary from about 20 mg/m² to about 100 mg/m².

[0965] An effective antineoplastic amount of epirubicin may vary from about 20 mg/m² to about 200 mg/m².

[0966] An effective antineoplastic amount of idarubicin may vary from about 1 mg/m² to about 50 mg/m².

[0967] An effective antineoplastic amount of mitoxantrone may vary from about 10 mg/m² to about 20 mg/m².

[0968] An effective antineoplastic amount of paclitaxel may vary from about 100 mg/m² to about 300 mg/m².

[0969] An effective antineoplastic amount of docetaxel may vary from about 50 mg/m² to about 100 mg/m².

[0970] An effective antineoplastic amount of vinorelbine may vary from about 15 mg/m² to about 30 mg/m².

[0971] An effective antineoplastic amount of cyclophosphamide may vary from about 100 mg/m² to about 1500 mg/m².

[0972] An effective antineoplastic amount of melphalan may vary from about 1 gm/m² to about 10 mg/m².

[0973] An effective antineoplastic amount of 5-fluorouracil may vary from about 100 mg/m² to about 1000 mg/m².

[0974] An effective antineoplastic amount of capecitabine may vary from about 10 mg/m² to about 1000 mg/m².

[0975] An effective antineoplastic amount of methotrexate may vary from about 10 mg/m² to about 1000 mg/m².

[0976] An effective antineoplastic amount of topotecan may vary from about 1 gm/m² to about 5 mg/m².

[0977] An effective antineoplastic amount of irinotecan may vary from about 50 mg/m² to about 350 mg/m².

[0978] In effecting treatment of a patient afflicted with a disease state described above a compound of formula (I) of the invention can be administered in any form or mode which makes the compound bioavailable in effective amounts, including oral and parenteral routes. For example, it can be administered orally, subcutaneously, intraperitoneally, intramuscularly, intravenously, transdermally, and the like. Oral or intramuscular administration is generally preferred. One skilled in the art of preparing formulations can readily select the proper form and mode of administration depending upon the particular circumstances, including the disease state to be treated, the stage of the disease, the form of administration of the selected cytotoxic agent and the manner of co-administration selected.

[0979] The selected antineoplastic agent can be administered by the appropriate route and dosing schedule as is well known and accepted for the particular agent. For example, epirubicin, doxorubicin, idarubicin, paclitaxel, docetaxel, 5-fluorouracil, cyclophosphamide and vinblastine can be administered intravenously. Idarubicin and cyclophosphamide can also be given orally.
